I know this is the 100th time you are seeing this and I've read through a number of emails pertaining to this but none seem to work...
In my test network I have a Windows Workgroup that consists of 2 XP PRO PCs and one XP Media Center edition. (basically pro)
I have ADNM installed on one XP PRO machine and have deployed netclient to all three machines (one that ADNM is on and the 2 others.)
XP SP2 is on all machines.
With XP SP2 firewall turned on on the media center PC, I CANNOT connect to virus chest. I get an RPC server is unavailable error. If I turn off the firewall it works fine.
When the firewall is turned on, I have gone in and put a check mark in the boxes for File and printer sharing, and remote Desktop. I have added TCP ports for 16111 and 16108. I have even uninstalled and reinstalled netclient on that machine. If the firewall is on, it won't work.
On the other hand, I have the other XP PRO machine that doesn't matter WHAT I do to the firewall, I can still access the chest. I have gone in and unchecked everything (File and printer sharing and remote desktop). I have not extra ports open and the firewall on. On that machine I STILL have no problem accessing the chest.
WHY?
and what else can I try on the media center PC?
I checked this out here because I have a similar problem on my larger DOMAIN based network with 65 PCs. I have a machine or 2 with the same scenario.
